Sejong Smart City Design Competition

Urban Design Studio for postgraduate students at ERICA Campus, Hanyang University, led by Networking City, is invited for the student design competition of ‘Sejong Smart City’ by Korea Land & Housing Corporation (LH).

Last January, Ministry of Land, Infrastructure and Transport of South Korea designated ‘5-1 Liveable Area of Sejong City’, a part of the new Korean administrative city, as a national testbed for Smart City and LH took responsibility to create the smart city from an initial plan and design to delivery for 2.74 km2 area.

To promote the interest from academics, industries and citizens and to share various ideas, LH invites six urban design studios from Korean universities and supports them to do good projects. The urban design studios will suggest inter-disciplinary ideas and have a joint exhibition in December.

Networking City’s studio accepts the LH’s kind invitation and makes efforts to create a better urban environment.
More news about the competition will be followed. 

‘Songdo: the hype and decline of world’s first smart city’ in ‘Sustainable Cities in Asia’

Routledge published ‘Sustainable Cities in Asia’ last September.
The book was edited by Federico Caprotti, Associate Professor in Human Geography at the University of Exeter, and Li Yu, Reader in Planning at Cardiff University.
It contains 23 chapters that show recent urban policies and practical challenges to build up sustainable cities in Asian cities.

I contributed Chapter 12: ‘Songdo: the hype and decline of world’s first smart city’ for the book. It looks at the history of Korean smart city policy, traces the twenty-five-year history of Songdo and critically reviews the reality of Songdo.

You can find more details of the book from Routledge’s webpage.

Mapping Protest in 3D with Twitter Data

As one part of my docotoral thesis, I have made the video that shows the relationship between ‘London End Austerity Now’ Protest on 20^th June 2015 and the Twitter acitivity on that day.

The video gives you some details about the protest, the data and 3D visualisation.

Mapping London’s Twitter Activity in 3d

Twitter Mapping is increasingly useful method to link virtual activities and geographical space. Geo-tagged data attached to tweets containing the users’ location where they tweeted and it can visualise the locations of users on the map. Although the number of the geo-tagged tweets is a relatively small portion of all tweets, we can figure out the density, spatial patterns and other invisible relationships between online and offline.

Recently, studies with geo-tagged tweets have been developed to analyse the public response to specific urban events, natural disasters and regional characteristics (Li et al., 2013) [1].  Furthermore, it is extending to traditional urban research topics, for example, revealing spatial segregation and inequality in cities (Shelton et al., 2015) [2].

 

Twitter mapping in 3D can augment 2d visualisation by providing built environment contexts and improved information. There are many examples of Twitter mapping in 3d such as A) #interactive/Andes [3] , B) London’s Twitter Island [4], C) Mapping London in real time, using Tweets [5]. A) and B) build up 3d mountains of the geo-tagged tweet on the map.  In the case of C), when the geo-tagged tweets are sent in the city, the heights of nearest buildings increase in the 3d model. These examples are creative and show different ways to view the integrated environments.

From a Networking City’s view, if we make a Twitter visualisation more tangible in a 3d urban model, it would help us to have a better understanding how urban environments are interconnected with the invisible media flow.

 

To make the visualisation, the Twitter data has been collected by using Big Data Toolkit developed by Steven Gray at CASA, UCL. All 53,750 geo-tagged tweets are collected on 20^th June, 2015 across the UK. As we can see from Table 1, the number of tweets was at the lowest point at 5am and reached to the highest point at 10pm with 3495 tweets. Moreover, Video 1 shows the location of the data in the UK and London on that day in real time.

 

Table 1. The Number of Geo-Coded Tweets in the UK on 20th June, 2015

 



Video 1. The location of Geo-Coded Tweets in the UK on 20th June, 2015

When we calculate the density of the data, London, particularly Central London, contains the largest number of the tweets. (Image 2)

 

 

 

Image 2. The density of Geo-Coded Tweets in the UK on 20th June, 2015

In order to focus on the high density data, 6 km x 3.5 km area of Central London is chosen for the 3d model. Buildings, bridges, roads and other natural environments of the part of London have been set in the model based on OS Building Heights data[6]. Some Google 3d warehouse buildings are added to represent important landmark buildings like St.Pauls, London Eye and Tower Bridge as you can see from Image 3, Image 4 and Image 5.

Image 4. The perspective view of Central London model

Image 5. The perspective view of Central London model (view from BT Tower)

The geo-tagged data set is divided into one hour periods and distributed on the map to identify the tweet density in the area. Through this process, we can see how the density is changing depending on the time period. For example, the tweets are mainly concentrated around Piccadilly Circus and Trafalgar Square between 10am and 11am, but  there are two high-density areas between 12pm and 1pm (See Image 6, Image 7, Image 8 and Image 9)

Image 6. The tweet density between 10am and 11am on 20^th June 2015

Image 7. The tweet density between 12pm and 1pm on 20^th June 2015

Image 8. The tweet density from 12am to 12pm

Image 9. The tweet density from 12pm to Midnight

 

 

As we’ve seen above, the 2d mapping is useful to understand the relative density in one period such as which area is high and which area is low between 12pm and 1pm. However, we cannot understand the degree of intensity in the highest peak areas. It is believed that 3d mapping is needed at this stage. We can clearly see the density of the tweet data in each period and the intensity of the tweet density across the time periods from Image 10 to Image 14.

West End area shows high density throughout the whole day but City area shows the peak only during lunch time. This pattern likely relates to the activities of office workers in City and leisure/tourist in West End.

A sense of new academic term

 

New academic term of UCL officially started on 22nd September 2014. Thousands of new students walk around the campus, and they fill Bloomsbury area with vibrant energy. Dr. Adam Dennett begun his GI Systems and Science class for new post-graduate students of CASA with welcoming slide on 1st October. In this year, CASA opened two new post-graduate courses: MSc SmartCities and Urban Analytics and MRes Smart Cities. Therefore, he has developed a lot of the course materials and structure for the students during last summer days.

 

On the same day, when CASA held SHOW AND TELL, which is a traditional CASA event to introduce each other, I apparently realised that the new term is just started! Most members of the lab came up and introduced themselves at this inaugural meeting.  

 

Emer Coleman’s seminar was followed on 7^th October under the title of “Open Data and the City: Looking back and Looking Forward”. She explained open data as a way of engagement and empowerment and how citizen can be benefited and can participate in making better urban environment. Several good cases, such as Hello Bristol, were mentioned.

After the presentation, many questions were emerging from the audience. Transparency, security, effectiveness and so on. However, I was uncomfortable when she criticised, with some sentences from Adam Greenfield’s “Against the smart city”, big corporations that IBM and Cisco have been pushing smart city idea for money rather than people or better society. I could not catch the difference between the big brands, which get profit by providing new city systems and solutions, and her company, which get profit as well by providing efficient transport solution and application. There might be a matter of size.

These adventures would be enough to feel a sense of the new term. However, UCL email was unusually hacked on 9^th October. All UCL students got 3000 emails (including me) with bello. It was a big issues not only in the campus but also in the UK as The Independentannounced. Steven Gray, a specialist of large datasets at CASA, analysed what has happened with his Big Data Toolkit and posted it on his blog.
 

A great urbanist_Peter Hall

The book cover of 'Cities of Tomorrow: An Intellectual History of Urban Planning and Design in the Twentieth Century'

Yesterday I was surprised when I searched some new journal articles through UCL library’s E-Journal service. Volume85, Number 5, 2014 of Town Planning Review that was published just some days ago includes a new paper of Professor Peter Hall. Unfortunately, it is still unable to look through the UCL service, ‘And one fine morning -’: reflections on a double centenary, the paper can arouse the glad to read his words as well as the grief losing a great urbanist who passed away on 30 July 2014.  

I, had trained as an architectural designer, started to have an interest in urban studies after reading one of his tremendous books ‘Cities of Tomorrow: An Intellectual History of Urban Planning and Design in the Twentieth Century.' The book carefully and attractively introduced the history of modern cities from the 19th century to the end of the 20th century and it unveiled hidden stories that had built on the characteristics of each city step by step. The most interesting point what I found in this book, his vision for the city is not heading for built forms, but alternative society as Ebenezer Howard pursued. And it was entirely enough to bring the young student to London. 

After I have entered The Bartlett, UCL, I had the opportunity to audit his seminar class for masters’ students. Every week, students groups analysed urban problems of particular cities in the world and studied how urban policies have intervened in the problems. When I listened his comments in the class, I could imagine Kung-Fu masters who simply overwhelmed many fighters in the movie what I watched long years ago . He looked like he knew everything about cities, and he was thoroughly conversant with geographical, economic and social issues from European cities to Sydney, Singapore and Global South. 

Recently, Regional Studies that Peter Hall worked as the first editor published a virtual special issue to commemorate him. In the editorial page, Nicholas A. Phelps and Mark Tewdwr-Jones admire him highly as the academic who “successfully brought together in his career – history, geography and planning” and explained his achievements based on his articles in the issue that you can freely access. 

I have made the list of his recent books.

The Planning Imagination: Peter Hall and the Study of Urban and Regional Planning

Good Cities,Better Lives: How Europe Discovered the Lost Art of Urbanism 

Sociable Cities:The 21st-Century Reinvention of the Garden City
Citiesof Tomorrow: An Intellectual History of Urban Planning and Design in theTwentieth Century

Also I have checked his lecture videos on online.
Youtube and Vimeo contain some his lectures, but the following videos might be useful to watch.

Connecting European regions through innovative transport technologies
Geography of a recession glimmers of hope?
New New Town: Peter Hall (Part 1 of 2)
New New Town: Peter Hall (Part 2 of 2)

I recommend seeing Michal Batty’s tribute for Peter Hall.

Hope this post could be helpful to remember Professor Peter Hall and his works

 

 

The techniques of urban design- Designing Cities: Basics, Principles, Projects

 

Image 1. The book cover of ‘Designing Cities: Basics, Principles, Projects’

 

What is the basic knowledge for urban design? Which techniques are necessary for designing decent urban spaces? ‘Designing Cities: Basics, Principles, Projects’, written by German architect Leonhard Schenk, is navigating the answer of these questions.

The book is structured along three parts,
1) General principles of urban design
2) Practical techniques for designing cities with relative examples

3) Three sensible examples that are recently constructed and well evaluated   - Hamburg (Germany), Tubingen (Germany) and Belval (Luxemburg)

When people want to make an overview from the basic theory to the completed projects, it seems a well organised book to look through all parts. 

 

The author argues that the most urban design projects have been realised by competitions, and two factors should be incorporated to win the competitions. On the one hand, projects need to satisfy the demands of the client and the jury. On the other hand, the functionality, the design and the representation capacity of projects have to be promoted by themselves. This argument clearly indicates the direction of the book. Over 350 pages, the author illustrates in detail the systematic methods for creating urban spatial organisations and visually attractive designs.

 

What an interesting point of this book is the explaining principles of urban design step by step, particularly in the Chapter 1 and 2. For example, ‘the law of similarity’ describes that ‘elements that resemble one another in the form are more readily experienced as belonging together than elements are. In addition, similar elements result in more uniform groups than dissimilar ones’. (P.21, See image 3) The principles demonstrate not the characters of each element but the natures of the group as a corporate body of the elements. These rules are underestimated because too simple and too obvious. But, we could easily deep in troubles during the design process if we do not keep them in mind. And then, from the Chapter3, the author starts to explain the practical ways of urban design such as designing urban blocks, various grid structures, organising building lots, road systems, designing public space and representation skills. 

From Rhythmanalyst to Rhythmconductor- Rhythmanalysis: Space, Time and Everyday Life

 

 

 

 

Image 1. The book cover of ‘Rhythmanalysis: Space, Time and Everyday Life’

 

In the book, Rhythmanalysis: Space, Time and Everyday Life, French sociologist Henri Lefebvre suggests ‘Rhythm’ as an alternative tool to understand and analyse everyday urban life beyond visual recognition. He argues that we can examine the true nature of cities from the human body, the basic unit of urban life, to substantial urban structures through rhythms.

 

Invisible rhythms are generating, repeating and transforming in cities. Lefebvre categorizes types of rhythm, which deeply intervene the life and make a foundation of law, institution and culture, based on its characteristics. Among them, the author particularly insists to pay attention to two aspects of rhythms that Arrhythmia which is creating discordance between or among two or more rhythms, and Eurhythmia which is staying in the state of harmony and balance. He asserts that it is important to convert Arrhythmia in the city that causes inequality and injustice to Eurhythmia which sustains healthy urban condition.

 

‘Rhythmanlysist’ is a fresh idea from the book published in 1992. Rhythmanlysist hears sounds of the city and reveals hidden systems behind visual images with sensing and analysing the change of spatial aspects in timing. As a rhythmanlysist, Lefebvre investigates Mediterranean cities. He presents some insights that the rhythms of Mediterranean cities are derived from specific geographical and climate environments, and the rhythms have created different political system and exceptional cultural diversity in contrast to Atlantic cities. Physically, it leads the development of plazas and the importance of stairways which link sloping lands.

 

Rhythmanlysist could still be a valuable concept to understand complex urban situations. However, we are living in the digital era. As Mitchell (Mitchell, 1999) denoted, the rhythms of our ordinary life are changing by digital communication. Every day tremendous data, which are invisible and inaudible, are generating, and its flows push us into the massive ocean of heterogeneous rhythms. Therefore, new Rhythmanlysist in the digital age needs other capacities. Capturing the digital data in real time and synthesizing it should be essential requirements to create or maintain Eurhythmia. While the cities of the 20^th century needed Rhythmanlysist, now it is the time of ‘Rhythmconductor’ who collects digital rhythms, reorganises its tempos-meters-articulations and resonates new contexts. We can easily find good examples of Rhythmconductor like below.

This radical change of the rhythm gives an opportunity to redefine the scopes of each social group. Citizens collect and utilize the data by their mobile devices; furthermore, they solve complex urban problems by themselves. (Desouza and Bhagwatwar, 2012) The role of planners is challenging to make new rhythms by spreading effective information and stimulating civic participation using social media instead traditional managers’ role within mainstream planning structures. (Tayebi, 2013) Also, Scientists’ role is shifting. According to Wright (Wright, 2013), scientific researchers had focused to find reasons of urban problems until the last decade, however; their voices are getting stronger to solve problems and provide alternatives in the decision making process with geospatial data and geographical analysis.

Protest is nothing new

 

Yes, throughout the history of human being, protests have been here and there though fresh protest news cover on GoogleNews every day. [i] [ii] If we only count massive protests from 19th century, there were strong collective voices of French Revolution in 1848, Russian Revolution in 1917, 1968 protests in the world and Eastern Europe in 1989, and these were the generator of social changes each time.    

Not going too far away till the 19th century, more than 200 million protests have impacted on the life of people since 1979 despite ignoring hidden and unknown events.[iii] However, the number of protest has not been increasing so far based on the data of GDELT which is a research group to collect global political unrest data and provide daily report with geo-spatial data. It would mean that as growing the opportunities to see the news about protests, we might believe that protests have been common than in the past.[iv]

 

What is the key factor to force people into the street?

Recently, Bridge, Marsh and Sweeting (2013) argue the change of governing structure, from government to governance, is the essence of recent protests.[v] According to their opinion, it stimulates governments work together with private sectors and communities, so the boundary of different organisations is blurring far more than before. The changing forms of the organisations extend to the shifting role of citizens, emphasizing new forms of networks and accountability, and finally the nature of democracy. Amid this transition, people are more interested in direct citizenship, and we have been readily watching one form of direct democracy, protest.

Meanwhile, Castells (2012) insists that we need to consider the transformation of communication to understand current protests.[vi] The development of internet technology facilitates that people can send messages many to many and share resources with horizontal-endless networks by themselves. On the internet, which is an autonomous space and no government control by Castells’ opinion, people try to change power relationships around them for ‘a better humanity’ when the relationships disrupt their life. When desires and goals of people are emerging in urban spaces beyond the internet, we could watch them such as Arab Spring and Occupy movements.
